INDICATOR.

Application led May 18, 1921, Serial No. 470,570. Renewed April 14, 1923.

10 all whoml t may concern.'

Be it known that I, NOAH S. HARTER, a citizen of the United States, residing at lVauliegan, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Indicators, of which'the following is a specification.

The invention relates to improvements in Indicators.

One of the objects of the invention is to improve recorders. A

Another object is to provide an impulse recorder which will record the maximum effect of the impulse.

Another object is to provide a recorder which will impose minimum resistance upon the associate means for producing the impulse.

, Another object is to provide an accurate, durable and reliable indicating device.

Another obj ect is to provide an indicating device that may be associated with a suitable target, to indicate the force and effect of a blow delivered to a golf ball in a practice game, more specifically disclosed in my copending application Ser. No. 470,569, filed May 18, 1921.

Other, further and more specific objects of the invention will become readily apparent, to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein Fig. 1 is a front view of the indicator embodying my invention. i

F ig. 2 is a section taken approximately on line 2-2 of F ig 3.

Fig. 3 is a section taken approximately ou line 33 of Fig. 2.y

In all of the views the same reference characters are employed to indicate similar parts.

The indicator is contained within the casing 5 having a hinged top 6 inthe center of which is a dial 7 under al glass front 8 thru which the index or pointer '9 may be seen. The dial is graduated and bears on its face numerals indicative of the number of yards a golf ball would be driven by an impact necessary to move the pointer 9 to the point corresponding with the respective indication, or in other words, the dial is, or may be, graduated to represent the relative impact or effect of an impulse that may be applied to ya cord or line 10, the movement of which is effective to rotate thel pointer 9.

The pointer 9 is fixed to a transverse shaft 11 which bears a drum12 around which the cord or line'lO is wound and to which it is fixed by interweaving the cord inside of the drum 12 so that the end 14; passing around the pulley 15 may be secured to the lower end 16 of a spring 17. The .shaft 11. is preferably supported in ball bearings 18 and 19 to reduce its resistance to rotation to a minimum. y

The shaft 11 also' bears a ratchet wheel 20 in normal engagement with which is a spring stressed pawl 21 supported on a transverse shaft 22 which is held yieldingly in Contact with the teeth 23 of the wheel 20 by means of the spring 24. The pawl 21 may be disengaged from the wheel by a downward pressure upon the outer end 25 of the pivoted lever 26, which lever is pivoted at 27, and has a short end 28, held downwardly by the spring 29,` and which engages the end 3() of the pawl 21. Stops 32 and 33 limit the movements of the lever 26.

Now, from the foregoing description, it will be manifest that when a pull is exerted on the cord 10, the d rum 13 on the shaft l1 will be rotated in proportion to the stress applied tothe cord. The spring 17 will resist the pull or stress applied to the cord 10 and will permit the drum 13 and the pointer 9 to be rotated proportionately of the applied force that moves it to that point.

After ithe impulse has beenl applied to the cord and the pointer moved on the dial by the effect thereof, observation is made of the recorder, and thepointer or index is released when it will be automatically re- Y turned to its normal position by effect of the spring V17. To release the pawl, it is only necessary to press down upon the end 25 of the pivoted handle 26, whereupon the inner end 28, engaging the end 30 of the pawl will move the pawl out of engagement with the teeth 23, thereby permitting the index, or pointer 9, to return to the zero position.

The effect of the spring 17 may be varied y by means 0f the adjusting screw 34 to bring the pointer back to zero, the spring having previously been properly calibrated with respect to the pointer rand the dial 7 over which it moves. The screw 34 is accessible at any time thru an orifice 35 made in the end of the casing The mechanism described is contained in a frame 36 properly secured to the casing.

The Wheel 15 around which the cord 10 passes is shown supported upon a shaft 37 in ball bearings 3S.

Vhile the device described is Well adapted for the purpose heretofore mentioned7 it also may be usedtor other purposes Yfor permanently recording the maximum effect of stress applied to the cord Whether it be a single impulse or a prolonged pull.

While I have herein shown a single embodiment of my invention and mentioned a special use to Which it is readily adaptable, it will be manifest to persons skilled in the art, that a number of changes may be made extended therefrom into Contact Witlrthe 'tree end of the spring; a paWl yieldingly bearing on said ratchet Wheel; a leverto release the paWl extending outside the casing; and means accessible thru a fixed Wall ot the casing vto adjust the tension of the spring.

In testimony whereof I hereunto subscribed my name.

NOAH S. HARTER.
